Who can tell us two reasons we call this substance “liquid gold”? Why would a foal need it and what happens if they need it but don’t get it?
Update/Answer: This is plasma, which is a commercial blood product taken from donor horse herds that are screened for diseases. It’s rich in gamma globulins, which are very important immune proteins. Foals normally absorb gamma globulins from a mare’s colostrum through their temporarily permeable intestinal wall in the first few hours of life. If the dam drips out her colostrum before the foal can nurse, if it’s poor quality, or if the foal is unable to nurse before the intestinal wall “seals” up, we give a IV transfusion of 1-3 liters of plasma to bring their levels up to normal.
I give ALL of our foals plasma routinely even if they get enough colostrum to further boost their immune systems, sometimes against specific diseases like Rhodococcus.
If foals don’t get enough gamma globulins from either colostrum or plasma their immune systems are severely compromised and they are susceptible to many different infectious diseases and conditions like infected umbilical remnants (“navel ill”) or infected joints (“joint ill”). Plasma’s ability to prevent that makes it invaluable.
Plasma is not cheap, since manufacturers must maintain herds of donor horses and the plasma is carefully processed and screened, so it’s liquid gold in terms of $!
